Abstract
LLC resonant converter is regarded as a promising future power conversion topology because of its outstanding characteristics such as high efficiency and low EMI noise. However, the designing procedure is complicated and the manufacturing is challenging. In this thesis, the operation of LLC resonant converter is investigated and a designing process of it using LED as output loading is proposed. In addition, the effect of the variation of each main component in this converter is thoroughly analyzed, and the selections of them are discussed, too. The designing method and the manufacturing process of integrated transformer are also proposed. A constant voltage and constant current control 100 kHz and 20W LLC resonant LED driver is designed and realized to verify the proposed method.
